Automatic Pelletizer with Hydraulic cutter advance
From 5 – 5,000 kg/hr Type Compact, AH

Pelletizing Technology
Automatic Pelletizer type AH D
Larger capacity pelletizers for Polymerization / Reactor lines.
Up to 35,000 kg/hr Solutions for large-scale
micropellet production
The adjustment of the Cutter Hub to the Die Plate is made automatically by means of a Hydraulic Cylinder.
For operator safety - Automatic connection of Water Box and Pelletizer via hydraulic locking mechanism.
Pelletizing TechnologyFully Automatic Hydraulic Blade Adjustment
12
1) Increase of hydraulic pressure
2) Rise of motor torque: indicates blades now in close contact with die face metal
3) Reduction of hydraulic pressure
4) Sharpening pressure5) Production pressure
Automatic Blade Sharpening set as an automatically
recurring function in your personalized program
Eliminate “tails”
Here’s how it works:
Pelletizing TechnologyFully Automatic Hydraulic Blade Adjustment
Customer Advantages: Constant pressure of the blades to the die plate
No blade “hopping” – hydraulic oil not compressible, unlike air or spring Maintain pellet quality independent of wear
Eliminate “tails” Fully automatic blade re-sharpening Low wear of blades and die plate
Precision control, use only the pressure you need Minimal operator intervention during operation
Operators can focus on other tasks No die face smearing Pelletizing of even the lowest viscosities

Die Plate for Micro-Pellets ø=0.4 mm, 1,110 holes
For AH 2000 pelletizer
Die Plates designed for Oil or Steam heating Pressure reduced die
plates, e.g. X-in-1 design
Designed and manufactured in-house by Nordson BKG ANSYS Fluent CFD Analysis / Solidworks FEA
Designed for an extensive variety of applications
15
Pelletizing TechnologyCutter hub design
45°Angular design Suitable for most polymers Especially important for softer materials
to prevent smearing on die face
Patented 90°“Straight” design Allows for more blades per hub Customer can operate with lower RPM to deliver
same capacity as angled-blade hub / conversely the available capacity is increased at higher RPM
Suitable for most polymers

Polygon Water Filtration SystemFor use in Combigon and Optigon systems
The BKG Polygon water filtration system is an automated, self-cleaning, tempered water system which minimizes operator intervention to help maximize productivity and reduces energy consumption in order to increase operating profit.
25
Why Polygon? Conventional UWP systems requiring fine filtration of the process water utilize a
secondary filter (curved sieve) external to the water tank. The use of a secondary filter requires installation of a 2nd process water pump to move
process water from the water tank to the top of the curved sieve and back to the tank.

Why Polygon?Manual vs. Automatic Cleaning
Conventional Polygon
Automated monitoring and self-cleaning of the Polygon filter drum
No operator intervention needed 70 micron filtration
Frequent monitoring by the operator required Manual scraping/cleaning of the curved sieve Manual emptying of the collecting drawer 150 micron filtration
27
Why Polygon?Energy savings The 2nd process water pump contributes
a considerable amount of energy consumption to the overall process.
Alternatively, the Polygon water filtration system eliminates this pump, and only a small motor (for rotating the filter drum) and gravity facilitate the fine filtration of the process water.
